A slot is a dynamic placeholder that either waits for content (passive) or is called upon to supply content (active). A slot can either reference an entity value or a targeter.

A casino slot machine is a mechanical device with reels that spin when a lever is pulled or a button is pushed. The machine pays out winning combinations if symbols line up on the pay lines. The number of possible paylines can vary from one machine to the next, and some machines offer multiple jackpot levels.

Slots can also be used to trigger different bonus games. The Starburst slot, for example, offers an expanding wild that covers a whole reel and rewards a respin when it appears on the screen. This feature, coupled with its high RTP and low volatility, makes this slot a top choice among gamers.
